Transumbilical selective angiography in the newborn

Area of Science:

• Neonatal imaging and interventional radiology.

Background:

• Selective angiography is crucial for diagnosing vascular abnormalities in newborns.
• Transumbilical access offers a minimally invasive approach for neonatal procedures.

Purpose of the Study:

• To present a refined method for transumbilical selective angiography in neonates.
• To identify optimal catheter characteristics for this specific technique.

Main Methods:

• The study details a transumbilical selective angiography procedure adapted for newborns.
• The Seldinger technique is employed for vascular access.
• A 5-French polyvinyl catheter is specified as the preferred instrument.

Main Results:

• The presented method facilitates selective angiography via the umbilical route in neonates.
• Side-hole catheters were found to be unsuitable for this application.
• The 5-French polyvinyl catheter demonstrated efficacy in achieving selective catheterization.

Conclusions:

• Transumbilical selective angiography is a viable technique for neonatal diagnosis.
• The choice of catheter is critical for procedural success, with 5-French polyvinyl catheters being recommended.
